I've been looking there, not many options. I might have to bite the bullet and buy new. I'm not even sure if there is much difference between knee boards and fish surfboards
There's a huge difference. I worked for a guy who made kneeboards. They were way different to any surfboards. I think he is making none right now actually.
Over and above width, thickness, rail and rocker differences, the fin cluster is in a completely different place.
